Channel coding in communications

Abstract

An apparatus may establish ( 401 ) a rateless radio link for stable semantic/effective communication, R2S2, between the apparatus and a client device, wherein for the R2S2 link a desired quality of service, QoS, is defined including at least a desired packet length range of from a minimum data packet length Lmin to a maximum packet length Lmax. The apparatus may schedule ( 402 ) a supported packet length Ltx and target stable bit error rate for transmission via the R2S2 link, wherein Lmin≤Ltx≤Lmax.

1 . An apparatus comprising:
 at least one processor, and   at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to,   establish a rateless radio link for stable semantic/effective communication, R2S2, between the apparatus and a client device, wherein for the R2S2 link a desired quality of service, QoS, is defined including at least a desired packet length range of from a minimum data packet length L min  to a maximum packet length L max ; and   schedule a supported packet length Ltx and target stable bit error rate for transmission via the R2S2 link, wherein L min ≤L tx ≤L max .   
     
     
         2 . The apparatus according to  claim 1 , wherein the desired quality of service, QoS, for the R2S2 link further includes at least one of a puncturing pattern, desired bit error rate range, desired latency budget, or desired service stability rate. 
     
     
         3 . The apparatus according to  claim 1 , further being caused to:
 establish a hybrid automatic repeat request, HARQ, feedback link or R2S2 feedback link between the apparatus and the client device, for transmission or reception of an ACK feedback signal or a NACK feedback signal, to respectively indicate whether the target stable bit error rate is within a desired bit error rate range or is higher, or   
       a multi-bit feedback signal to indicate a deviation of the target stable bit error rate from the desired bit error rate range. 
     
     
         4 . The apparatus according to  claim 1 , wherein the apparatus is, comprises, or is comprised in a network node, such as a gNB, eNB or wireless local area network access point. 
     
     
         5 . A device comprising:
 at least one processor, and   at least one memory storing instructions that, when executed by the at least one processor, cause the device at least to,   perform, by an application, a rateless joint source and channel coding, JSCC, that encodes an original data packet into a string of bits by bit-wise treatment or into a string of symbols by symbol-wise treatment.   
     
     
         6 . The device according to  claim 5 , being caused to:
 reduce, by a radio network client by using a puncturing pattern, the string of bits or string of symbols, into a punctured data packet to be transmitted in uplink with a target stable bit error rate scheduled by a network apparatus, such that the punctured data packet has a supported packet length Ltx scheduled by the network apparatus.   
     
     
         7 . The device according to  claim 5 , wherein
 a minimum packet length of the punctured data packet is guaranteed with a desired bit error rate, wherein a packet length of the punctured data packet is shorter than that of the string of bits or string of symbols.
